No namespaces. No templates but macros. No exceptions. No C++.
Sorry, I beg to differ. BTW, they say themselves that they tolerate but not
use exceptions, so they actually need two-stage construction if construction
can fail, and for exactly the guessed legacy reasons.

A C++ object is not a window, it is rather a proxy for managing the window.
As such, it can be attached or detached from the underlying window, just
like a std::fstream, so in this light it makes sense actually. Thanks for
